    Synopsis
    ========

    RealPlayer is vulnerable to a heap overflow that could lead to remote
    execution of arbitrary code.

    Background
    ==========

    RealPlayer is a multimedia player capable of handling multiple
    multimedia file formats.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-video/realplayer < 10.0.5 >= 10.0.5

    Description
    ===========

    RealPlayer is vulnerable to a heap overflow when opening RealMedia
    files which make use of RealText.

    Impact
    ======

    By enticing a user to play a specially crafted RealMedia file an
    attacker could execute arbitrary code with the permissions of the user
    running the application.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All RealPlayer users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-video/realplayer-10.0.5"
